SHURE SLXD2+/K8B | Digital Wireless Handheld Microphone W/ K8b Capsule

SLXD2+/K8B

Digital Wireless Handheld Transmitter with KSM8 Cardioid Capsule (G57: 470 to 608 MHz)

SLXD2+ is a professional digital wireless handheld microphone transmitter designed for use with Shure SLX-D+ receivers. Ideal for live performance, installed sound, and houses of worship, it delivers transparent digital audio, secure RF performance, and advanced remote control capabilities in a rugged aluminum, stage-ready form factor with a backlit LCD screen for essential information. This version is equipped with a KSM8 dynamic cardioid mic capsule.

KSM8 Dualdyne Cardioid Vocal Dynamic Capsule

The KSM8 features an innovative dual-diaphragm dynamic capsule that minimizes proximity effect, delivering a consistent sound, even when the distance between the mic and the sound source varies. The microphone is engineered to provide sound professionals with the signal clarity typical of condenser microphones without processing, along with the reliability of dynamic microphone feedback control. The cardioid polar pattern picks up less background sound and delivers a clean, richly detailed signal, great for speech and vocals in live venues.

Transparent Digital Audio and Expanded RF Performance

 When paired with an SLX-D+ receiver, the SLXD2+ delivers transparent 24-bit digital audio with greater than 118 dB of dynamic range. A wide tuning bandwidth of up to 138 MHz (regionally dependent) supports flexible frequency coordination and reliable operation across a wide range of venues. The platform supports high channel counts in dense RF environments, making it suitable for scalable wireless deployments.

ShowLink Ease Remote Transmitter Control

ShowLink Ease enables real-time, two-way communication between the SLXD2+ transmitter and a compatible SLX-D+ receiver using BLE transmission. Once linked, the transmitter automatically follows receiver frequency changes across power cycles. Engineers can remotely adjust frequency, RF power, and control locks, apply interference mitigation, and perform over-air firmware updates without handling the microphone or requiring an IP network.

Interchangeable Capsule Design

The SLXD2+ features an interchangeable capsule design, allowing users to tailor the microphone to specific applications. In addition to the included KSM8, compatible Shure capsules include the Beta 58A, Beta 87A, SM58, Nexadyne 8/S, and Nexadyne 8/C, offering a range of pickup patterns and sonic characteristics.

Secure Operation and Flexible Power Options

 The SLXD2+ supports AES-256 encryption for secure wireless transmission. It operates for up to 8 hours using two AA batteries, with support for optional Shure SB903 lithium-ion rechargeable batteries. When used with compatible Shure charging accessories (available separately), rechargeable batteries provide precise runtime readouts in hours and minutes directly on the transmitter display.
